1.has an over-the-ear form
Comfortable full-size form with earcups that fully enclose your ears. This model is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors. It offers potential for maximum bass and loudness levels.
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
The device comes with its own special case or pouch, which is useful for safe transportation.
A long cable ensures more freedom of movement.
A coil cable offers more flexibility, as it can be further extended when in use, as well as retracted to take up less space when not in use.
